Projection device and method for controlling projection device

A projection device, comprising:

• a display panel including a pixel circuit including a first capacitance element and a second capacitance element, and a light-emitting element that emits light, having luminance corresponding to a current, in a predetermined direction, wherein in a first period, a voltage corresponding to a current supplied to the light-emitting element is held in the first capacitance element, in a light-out period after the first period, the light-emitting element is off, in a second period after the light-out period, a current corresponding to the voltage held in the first capacitance element is supplied to the light-emitting element, and a voltage corresponding to the current supplied to the light-emitting element is held in the second capacitance element;
• and
• an optical path shifting element configured to shift an optical path of light emitted from the light-emitting element to a first and second optical paths, wherein shifting is performed from the first optical path to the second optical path in the light-out period, and the second optical path is maintained in the second period.
